Minimal Emacs

Intermediate users might prefer to turn off or customize Toolbar, Menubar and Scrollbar. This provides a distraction free environment and maximizes the screen area available for coding or text editing.

M-x customize-variable RET tool-bar-mode: Turn off toolbar

M-x customize-variable RET menu-bar-mode: Turn off menubar

M-x customize-variable RET scroll-bar-mode: Turn off scrollbar.

M-x customize-variable RET blink-cursor-mode: Also see M-x customize-group RET Cursor RET

-Prior to Emacs 24 the most popular way to incorporate custom color themes into Emacs was the [http://www.emacswiki.org/emacs/ColorTheme color-theme package]. While it usually got the job done it had some problems that we won’t be discussing here and more importantly - it’s a third-party package, that’s not part of Emacs proper.

-[http://batsov.com/articles/2011/08/19/a-peek-at-emacs24/ Emacs 24] finally introduced a new standard way of dealing with color themes (based on Emacs’s built-in [[Custom|customize]] facility). While it doesn’t have a proper name (as far as I know) it’s commonly referred to as the <tt>deftheme</tt> facility, since <tt>deftheme</tt> is the name of the macro you’d use to create such a theme. ( <tt>deftheme</tt> has actually been around since Emacs 23, but it was heavily improved in Emacs 24 )
+== Adding and changing key bindings ==
-Emacs 24 comes with a selection of built-in themes that you can choose from, so you’re no longer bound to the default theme (which many find quite ugly). To choose a new theme just do a <tt>M-x load-theme</tt> (tab completion is available for the names of the available themes). At this point you can give the command a try with the <tt>tango</tt> theme. If you like a theme so much that you’d want to use it all the time you can put in your Emacs configuration (<tt>.emacs</tt> or <tt>init.el</tt> for instance) like this:
+== CUA mode ==
-<pre class="cl">(load-theme 'theme-name t)</pre>
+== Line wrapping ==
-If you’d like to return to the default-theme just do a <tt>M-x disable-theme</tt>.
-How do you create a <tt>deftheme</tt> theme? Quite simply actually - just do a “M-x customize-create-theme”. You’ll be presented with an UI prompting you for a theme name, description and faces. After you save the theme a file called <tt>name-theme.el</tt> will be written on your filesystem. Here’s its skeleton:
+== Region, selection, transient-mark-mode ==
-<syntaxhighlight lang="lisp">
-(deftheme demo
-  "Demo theme")
-(custom-theme-set-faces
- 'demo
- ;;; list of custom faces
- )
-(provide-theme 'demo)
-</syntaxhighlight>
-There was also an online theme generator [http://elpa.gnu.org/themes/ here], but it seems to be down at the moment.
-If dislike customize, you can just have a look at the source code of the built-in tango (or any other) theme and use it as a reference.
-Once you’ve created the new theme you’ll have to drop it in a folder that’s on the <tt>custom-theme-load-path</tt>. I’d suggest the following:
-<pre class="lisp">(add-to-list 'custom-theme-load-path &quot;~/.emacs.d/themes&quot;)</pre>
-If you’re an [https://github.com/bbatsov/emacs-prelude Emacs Prelude] user you’re already covered. This folder exists and is automatically added to <tt>custom-theme-load-path</tt> by Prelude, so all you have to do is drop there the themes you’d want to try out.
-You may find the [http://julien.danjou.info/software/rainbow-mode rainbow-mode] useful when developing color themes. If fontifies strings that represent color codes according to those colors. The mode is known to be a great addition to css-mode, but I find it very helpful with color theme development as well. It’s also included (and enabled) in Prelude by default.
-The Emacs package manager <tt>package.el</tt> (formerly known as ELPA) is gaining a lot of popularity lately and the community [http://marmalade-repo.org/ Marmalade] repository already houses a few Emacs 24 themes that you can install from there. If you’re developing a theme that you’d like to submit to Marmalade it’s imperative that the theme modifies the <tt>custom-theme-load-path</tt> in an <tt>autoload</tt> - otherwise it won’t be of much use. Add the following snippet (or something similar) before the <tt>provide-theme</tt> line if your custom theme:
-<syntaxhighlight lang="lisp">
-;;;###autoload
-(when load-file-name
-  (add-to-list 'custom-theme-load-path
-               (file-name-as-directory (file-name-directory load-file-name))))
-</syntaxhighlight>
-I’d also advise you follow the proper naming convention <tt>name-theme.el</tt> so that it’s apparent that your theme is <tt>deftheme</tt> compatible.
-Oh, and one more thing - porting themes from color-theme to deftheme is really simple (just have a look at the old and the new version of Zenburn in its repo), so you should really consider porting all the themes you maintain to <tt>deftheme</tt>.
